As shown in the figure, ARID1A or ARID1B expression was related to immunosuppression in 517 lung adenocarcinoma (LUAD) samples and 501 lung squamous cell carcinoma (LUSC) samples, which is mainly characterized by significant reductions in the abundances of activated CD8+ T cells and activated dendritic cells (DCs). This evidence concerns the gene CD8A and squamous cell lung carcinoma.
